Helix is working on a plugin system that will hopefully allow for copilot (or whatever other product) use.

Also, the Helix way, thus far, has been to build a LSP for all the things, so I guess you'd make a copilot LSP (I be there already is one).




Unless something's changed, every AI-backed language server I've tried in Helix suffers from the same limitation when it comes to completions: Suggestions aren't shown until the last language server has responded or timed-out. Your slowest language server determines how long you'll be waiting.

The only project I know of that recognizes this is https://github.com/SilasMarvin/lsp-ai, which pivoted away from completions to chat interactions via code actions.


I feel like an LSP is very insufficient for the ideal UX of AI integrations. LSP would be fine for AI autocompletes of course, but i think we want a custom UX that we don't quite yet know. Eg what Zed offers here seems useful. I also really like what Claude Code does.

I don't know the LSP spec well enough to know if these sort of complex interactions would work with it, but it seems super out of scope for it imo.
